What are the effects of gasoline?
What are the potential health effects of gasoline? 1 Inhalation: Can irritate the nose and throat. Can harm the nervous system. Symptoms may include headache, nausea, dizziness, drowsiness and confusion. A severe exposure can cause unconsciousness. 2 Skin Contact: May cause mild irritation. Repeated or prolonged exposure can irritate the skin. Not expected to be absorbed through the skin. Any skin contact will also involve significant inhalation exposure. 3 Eye Contact: Not irritating. 4 Ingestion: Can irritate the mouth, throat and stomach. Can cause effects as described for inhalation. Aspiration hazard. May be drawn into the lungs if swallowed or vomited, causing severe lung damage. Death can result. 5 Effects of Long-Term (Chronic) Exposure: Can cause dry, red, cracked skin (dermatitis) following skin contact. Gasoline is a complex mixture containing as many as 250 separate hydrocarbons including several with well-established toxicity (e.g., benzene, toluene, xylenes, and n-hexane). However, there is little information available regarding the potential effects from long-term occupational exposure to gasoline itself. Most of the information available relates to neurotoxic effects from intentional long-term abuse or "sniffing" of gasoline. These extreme exposures are not relevant to occupational exposures. Effects on the blood, which have been seen in some studies, are most likely from the presence of benzene or lead in the gasoline. 6 Carcinogenicity: Possible carcinogen. May cause cancer based on animal information. Has been associated with: cancer of the blood or blood system, kidney cancer.
